Abstract
- The interfaces between heavy metals and antiferromagnetic materials have garnered significant attention due to their interesting physical properties. La<subscript>0.35</subscript>Sr<subscript>0.65</subscript>MnO<subscript>3</subscript> (LSMO), as a typical manganite, exhibits an antiferromagnetic ground state that can be controlled through epitaxial strain and interfacial spin–orbit coupling. In this work, we reported the diverse magnetoresistance, influenced by the interfacial magnetic state, in Pt (3 nm)/LSMO (6–20 nm) heterostructures. The strong spin–orbit coupling of Pt and Dzyaloshinskii–Moriya interaction alter the spin structure and enhance the electron scattering at the Pt/LSMO interface, resulting in positive magnetoresistance. The interfacial angular-dependent magnetoresistance modulated by the interfacial magnetic states was also observed in the Pt/LSMO (20 nm) heterostructures. Our findings contribute to a broader understanding of interfacial properties between heavy metals and antiferromagnetic manganites. [ABSTRACT FROM AUTHOR]
